Aegis® H55C2ZP copolyamide resin is supplied in sealed containers and drying prior to processing is not required. However, high moisture is the primary cause of processing issues. If drying becomes necessary, a dehumidifying or desiccant dryer operating at 80°C (176°F) is recommended. Drying time is dependent on moisture level.

Recommended Melt Temperature Range

Melt Temperature: Recommended range is 230-275°C (446-527°F)
